I don’t think we have a setting to disable this one… you can hide **all** composer popup messages entirely with CSS (added to admin → customize → themes)… we already do this on mobile devices, so you wouldn’t be hiding anything critical by doing this:

```css
.composer-popup-container {
 display: none !important;
}

```

The similarity warning can be disabled by changing the `max similar results` site setting to 0. Though, worth mentioning that we use it on our own internal community and it does prove useful from time to time.
